Investigation of natural compounds by the HPLC method II. HPLC fingerprint method for the epigeal organs of Ferula kuhistanica and F. tenuisecta

A microcolumn HPLC fingerprint method has been developed for the epigeal organs ofFerula kuhistanica andF. tenuisecta. The possibility has been shown of control by the microcolumn HPLC method of the qualitative and quantitative yields of ferutinin in the initial plant raw material and in preparations extracted from it, and also at each stage of the isolation of the desired product. The method is universal and does not depend on species and chemical composition of the plant. Institute of the Chemistry of Plant Substances, Uzbekistan Academy of Sciences, Tashkent.

An investigation of the alkaloids of Lolium cuneatum

Summary In addition to three known alkaloids, the seeds ofL. cuneatum have yielded N-formylloline, N-acetylnorloline, and the new alkaloids N-methylloline and N-formylloline methiodide.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Dynamics of the accumulation of the alkaloids ofReseda luteola structure of lutine and lutinine

Summary The biosynthesis of the alkaloids ofAmmothamnus lehmannii Bge. have been studied by supplying the plants with [1,5-¹⁴C₂] cadaverine. It has been shown that cadaverine is a precursor of sophocarpidine, sophocarpine, and pachycarpine. Possible routes of interconversions have been studied by supplying the plants with the tritium-labelled alkaloids [³H] sophocarpine, [³H] matrine, and [³H] pachycarpine.V. I.

Structure of the acylated flavonol glycoside haploside D

From the epigeal part ofHaplophyllum perforatum (MB.) Kar. et Kir. has been isolated the new flavonol glycoside haploside D, C₃₀H₃₂O₁₈, mp 225–228°C, [] _D ²⁰ -212° (c 0.17; CH₃OH) for which, on the basis of chemical transformations and spectral characteristics the structure of haplogenin 7-0-[6-0-acetyl-2-0--L-rhamnopyranosyl--D-glucopyranoside] has been established.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Esters ofFerula rubroarenose

Summary Three new esters, in addition to six known esters, have been isolated from the roots ofFerula rubroarenosa Eug. Kor. On the basis of chemical and spectral characteristics rubaferin, rubaferinin, and rubaferidin have been assigned the structures of isovanilloylborneol, and 8-vanilloyl- and 8-p-hydroxybenzoylugamdiol, respectively.Translated from Khimiya Prirodnykh Soedinenii, No. 6, pp. 712–715, November–December, 1978.
